im a civil engineer and im drawing up road strata plans or OHS work floor drafts almost everyday for employers.but never (bear in mind i occasionally work with architechts and theyr the gayest bunch of designers iv come across! no theory or grounding, only artsy-fartsy flair) have i come across something so.. well, in depth.(or maybe its just my ignorance on the subject that makes me feel in awe)

erm, if anyone has more information on the amber box, kindly post where i may view it.i googled it and guess what popped up?UGN Security :p

if you want to start phreaking build yourself a beige box...thats a essential tool of the trade...also if you have local telephone company toll booths and a mp3 or cd player build you (or record you) a redbox...

*edit*I was reading the drawings...they look like something similar i'v seen before...what exactly does the amber box do shadow?

If you read the schematic it looks like it's just supposed to listen to the conversation by tapping into the phone line at some point and display an optical signal when the line is being used. Looks like a beige box to me.
